Steak ‘n Shake has added $5 million worth of Bitcoin to its reserves as it continues funneling all proceeds from Bitcoin payments directly into the fund.

“Our self-sustaining system, improving food quality that grows same-store sales that then grow the SBR, is transforming the chain via financial technology,” Steak ‘n Shake wrote in a Jan. 27 X post announcing the development.

With the latest addition, the fast food restaurant chain’s total holdings have now hit $15 million, which equates to approximately 168.6 BTC at the time of writing. It’s unclear whether these figures include price appreciation, customer payments, or additional undisclosed treasury activity.

Last time the company disclosed an update was on Jan. 18, when it said it had added $10 million in notional value to its Strategic Bitcoin Reserve.

Steak ‘n Shake and Bitcoin

Since introducing Bitcoin payments back in May last year, the company has increasingly embraced the move as part of a broader digital strategy and has even credited Bitcoin for directly improving same-store sales growth in 2025.

The company claims that it has saved nearly 50% in transaction fees by processing purchases via the Lightning Network instead of traditional credit card rails.

“We are trouncing our competitors thanks to growing support from our loyal customers and our Bitcoin champions,” it wrote at the time.

Recently, it has disclosed plans to further integrate Bitcoin into its operations by offering Bitcoin bonuses to hourly employees at company-operated locations. It partnered with Fold, a Bitcoin-focused rewards platform, to roll out the initiative.

Fold first partnered with the company in October to offer diners $5 Bitcoin rewards on purchases of special menu items like the Bitcoin Steakburger.

Although the news drew praise within crypto trading circles, the announcement also sparked backlash due to a condition that requires employees to remain with the company for two years before being able to access their Bitcoin bonuses.

Yet the latest addition to the company’s reserve goes to show that it remains committed to stacking Bitcoin through operational flows rather than relying solely on direct investments.

On the other hand, Bitcoin adoption among public companies throughout 2025 soared as the flagship crypto printed fresh highs in October. Although Bitcoin has since pulled back and lost a notable chunk of value, data from BitcoinTreasuries.net shows that roughly 1.13 million Bitcoins are still held by public treasury companies.
